This invention pertains to an apparatus showing the position of thevalve under-diffor curing meats and more particularly to ferent operatmgconditions. an improved apparatus for the treating of Referrlng moreparticularly to the draw- I meats by the in ection of a fluid into thearlugs and especlally toFigures 1 and 2, I 5 t i th f, show a containerfor curing fluids, or a brine It is the object of the present inventionto tank 10.

seen that by moving ports 29a,

29,30 and 31 formed in the valve The exterior of the cap 34 is providedwith stops 36, which limit the movement of the handle 33 andconsequently the rotation of the valve member 32 within the f valvebody. The port 29a within the valve member is of such a size that it isin communication with the intake port 29 of the valve at all timesduring its limited move-' ment while the ports 30a and 3111 are of approximately the same size as the ports30- and 31.

. Referring to Figure 1, it may be seen that the intake port 29of thevalve is in commu-- A nication with the pump. The discharge port 30leads to the needle 18, and the return portsure passing through theneedle flows through the arteries following the natur course taken byblood in these arteries; When the arteries become full, the pressureWhen the fluid is seen to ooze from the outer surface of the meat, themeat has been thoroughly treated and is-removed, and this procanotherpiece of meat to It has been foundthat for different types of meat,diflei ent pressures are required to procure the best results. 111 orderto obtain varying pressures, the handle 33 of the valve 21 is moved tocause various positions of the ports 30a and 31a with respect to theports 30 be adapted. to

o'vementof the handle to the right would reverse the positions of theseports, and by "moving the handle to intermediate positionsi either oneof the ports may be". opened the other closed to. any desired degree.

When the port 30 is open, the. full pressure of the pump13 is exertedthrou h the needle 18. When the port 30 is partially "closed, some ofthe fluid under pressure is permitted to es- Y cape through, the returnport 31 and the hose 37 back the'line between the pump and the veinneeinto the brine tank. The pressure in die is indicated on the gauge 22for the convenience of the operator.

A further advantage of thevalve 21 lies I in the fact that the ports 30and 310 are so 30amama for cooperation with The vein neev 31 that whenit is desired to shut off the flow through the port 30 altogether, aconnection is formed between the'ports 31 and 31a before the port 30 isentirely losed, making it impossible to build up an e cessive pressurebetween the pump 13 and the valve 21.

The valve '21 has an electric snap switch 38 of standard design securedto it. This switch is interposed in a conducting wire 38,

positloned with respect to the ports 30 and which forms a part of thecircuit to the motor 12. The switchis operated by means of a lever 40resiliently held in an upward position by av spring 41'. A projection 42on the handle 33 of the valve contacts with this .lever when the port 30is open. This 1 pletes the circuit through the conducting wire 39,energizing the motor 12. When the port 30 is closed, the lever 40 on theswitch is re-' leased and the motor is dmenergized; this, as

soon as the fluid under ressure is cut off from the needle 18, the mtor12 is automatically 'de-energized and the pumping operation ceases.
